Even small teat lesions are significantly associated with subclinical mastitis and the risk of mastitis increases as the lesions approach the teat canal. Analyses show that at least 7% of cases of subclinic mastitis would have been avoided if no teat lesions had occurred in the herd in question. Analyses also indicate that the risk of mastitis in a quarter increases by about 50% across a 10 months follow-up period (equivalent to one lactation period) after the teat has been injured.
即使是很小的乳头病变也与亚临床型乳腺炎显著相关，并且随着病变靠近乳头管，患乳腺炎的风险会增加。分析表明，如果相关牛群中没有发生乳头病变，至少7%的亚临床型乳腺炎病例是可以避免的。分析还表明，在乳头受伤后的10个月随访期（相当于一个泌乳期）内，一个乳腺区患乳腺炎的风险会增加约50%。
